Last Wednesday, October 14, 2020, the journal Environmental Science & Technology Letters published an article by the Environmental Working Group (EWG) on PFAS (“Population-Wide Exposure to Per- and Polyfluoroalkyl Substances from Drinking Water in the United States”).
From the EWG Press Release:
“A peer-reviewed study by scientists at the Environmental Working Group estimates that more than 200 million Americans could have the toxic fluorinated chemicals known as PFAS in their drinking water at a concentration of 1 part per trillion, or ppt, or higher. Independent scientific studies have recommended a safe level for PFAS in drinking water of 1 ppt, a standard that is endorsed by EWG.”
